Since the option was limited, I reluctantly put a B nib for my Niagara. I have tried to find a BB
rhodium-plated solid 18 karat gold nib. I just wonder if BB M625 nib is what I am looking for.
In this case, could someone tell me where I can purchase one. The Swisher Pen ad says thay sell
M625 nibs, but the description says that they are two-tone color nibs. I am afraid that they mght
be M650 nibs.
